/**
* We extend node:crypto APIs during builds and revalidates to ensure that prerenders don't observe random bytes
* When dynamicIO is enabled. Random bytes are a form of IO even if they resolve synchronously. When dyanmicIO is
* enabled we need to ensure that random bytes are excluded from prerenders unless they are cached.
*
*
* The extensions here never error nor alter the underlying return values and thus should be transparent to callers.
